Are the values of your components correct? (resistors, capacitors etc.)

Is your IC in the right way round?!?

Hmmm… I can’t see any faults. I wonder if this is a red herring, I’ll double check. I’ve checked the position of the base, collector and emmiter using the transistors datasheet found here: NPN datasheet BC109.

I still can’t find anything, all the polarised components are ok, no loose or broken connections, the values are ok… time to power up.
